IMPROVEMENT Ihl' PHYSIOLOGICAL BATTERIES.

The Schedule referred to in these Letters Patent and maklng part of thesame To whom it may concern.-

Be itiknown that I, ALFRED Gimmes GARRATT, of Boston, county of Suffolk,and State of Massachusetts, have invented an Improved Physiological orButtoM-Battery; and do hereby declare the following to be a -fnll,clear, and exact description thereof, reference being bad to theaccompanying drawings, in which- Figure l is a front view of my improvedbattery.

Figure 2 is also a front view, in which is shown a different arrangementof the buttons or disks.

Figure 3 shows the back of my battery, exhibiting the mannerot'connecting the buttons or disks.

This invention is an improvement on a physiological battery, patented bymyself, December 29, 1868,

aml has for its objects, the attainment of greater elasticity inapplication; the production oi'a simple oneelement battery as a whole;the result of this construction being, that I utilize the equivalent ofa copper and zinc pair ot'.platcs.

The nature of my invention consists in adjusting buttons or disks ofcopper or silver, and of zinc or al loy, or their equivalents indissimilar metals, upon flexible insulation as a baso, with suremetallic con-" nected, upon the-back oi the battery, by copper wires,

ll d, which connect in all dircetions---crosswise, diagonally, lengthwise, &o.-making themetallieconnections of the copper and zinc buttonsperfectly sure.

' Between the flexible back 13 and the front, 1s rubber or otherinsulation. for protection against outside in- The arrangement shown infig. 2 is'on the same principle, enera lly. The copper buttons aresurrounded by the zinc orjalloy buttons, thus making the copper buttonsthe centres of circles.

' The superior flexibility of this improved battery buttons or disksupon a base, the whole being flex-- ible.

This improved battery is battery, as a whole; that is, the copperbuttonsare as but one in action, and the zinc inalloy, though a dozen innumber, are as but one, and all the insular tjon-spaces between allthese bits of metal areas but onein action; and the result is, I utilizethe equivalent of a zinc and copper pair, which, if one, would beunyielding, and-incapable of adjustment to uneven surfaces. V

The use of the single element of zinc and copper is valuable, and wellknown to the medical profession in the whole world, but has only beenmade of stiff and uncomfortable materials, and impracticable, becauseit'eould not-be adapted to the parts desired with a surihcc large enoughto etfect'a cure; consequently,

. thi'sis a thing old and well known, but improved and utilized; and,by-iny invention, this single-element battery is made veryzvailable, forif thus manufactured, and kept for salc,;theprofessiou and the public atlarge would employ a' thousand where one battery of single element isnow used. v What I claim, therefore,asiny invention, and an improvementonbattery patented December 29, 18%, and desire-to secure by LettersPatent, is- The arrangement ofbuttonsa a, e c,

metals, upon a flexibleuomconductlng base, A, insulated fronrthe back13, the buttons connected by wires (1 (I, the whole forming asingle-element physiclogical battery, substantially as herei rset forth.

Intestimony whereof,'I have signed my name to this specification in thepresence of two subscribing witnesses.
